One of the Office updates may address a recently-disclosed zero-day flaw in several versions of Microsoft Office. Opening a specially crafted Excel file may permit an attacker to execute arbitrary code.
Microsoft said Monday that it was investigating what it called "very limited" reports from the field regarding Microsoft Excel files that exploit a vulnerability in certain versions of Microsoft Office, including: Microsoft Office 2000, Office XP, Office 2003, and Office 2004 for Mac. The company added that a fix was being developed.
The software giant is also dealing with at least four zero-day flaws in Word, though it remains to be seen how many of those issues will be fixed this month.
"Although we do not anticipate any changes, the number of bulletins, products affected, restart information and severities are subject to change until released," Microsoft said.
